<div style="margin-top: 0px; margin-bottom: 0px;" class=""> The N2 banks have been placed, the backup manifold has been installed and N2 flow has been established. MV4 is closed and will remain so until you are ready, this allowed us to complete everything
with no interruption of N2 flow. I will update the P&I and send it to you on Monday. One bank is set to ~12psig and the other is just under 10 this should allow us to use the banks one at a time if the need ever arises.<span class="Apple-converted-space"> </span><br class="">

<div style="margin-top: 0px; margin-bottom: 0px;" class=""><br class="">
</div>
<div style="margin-top: 0px; margin-bottom: 0px;" class="">Just to review what we talked about in the hall this morning and get some clarification from you:</div>
<div style="margin-top: 0px; margin-bottom: 0px;" class=""><br class="">
</div>
<div style="margin-top: 0px; margin-bottom: 0px;" class="">You all are moving the two 12-bottle N2 banks to the top of the pi tower and will run a gas line from there to the RICH N2 panel. Bank #1 will have a regulator set to ~20 psi and Bank #2' regulator
will be set to ~10 psi. This will allow gas to be supplied from Bank #1 until its pressure drops below 10 psi, at which point, Bank #2 will start to supply N2.</div>
<div style="margin-top: 0px; margin-bottom: 0px;" class=""><br class="">
</div>
<div style="margin-top: 0px; margin-bottom: 0px;" class="">Using the attached drawing as a reference, you're going to install the new backup manifold at MV4 rather than what is shown in the drawing. The house N2 supply will remain connected to and flowing through
MV1.</div>
<div style="margin-top: 0px; margin-bottom: 0px;" class=""><br class="">
</div>
<div style="margin-top: 0px; margin-bottom: 0px;" class="">Once the backup manifold is installed, DSG will run the cabling for the pressure transducers on the manifold to the hardware interlock cRIO and move the house nitrogen from MV1 to the new backup manifold
at the connection point labeled "N2 Gas From 96B".<br class="">
</div>
<div style="margin-top: 0px; margin-bottom: 0px;" class=""><br class="">
</div>
<div style="margin-top: 0px; margin-bottom: 0px;" class="">We want to make sure that whatever the plan is for the installation from the manifold, that N2 flow to RICH not be stopped for more than a few minutes. Since we discussed that MV4 will remain valved
off until DSG runs the PT cables, can you all be sure to leave the house N2 supply line attached to MV1 and flowing after you all install the backup manifold?</div>
